Claims. (C1. 139-255) This invention relates to a bobbin receptacle for looms and more especially to a device of this character which is capable of being rotated into and out of bobbin receiving position relative to the loom shuttle box.

In automatic weft replenishing looms, a battery is usually provided for holding a plurality of iilled bobbins, so that when the bobbin in the loom shuttle becomes empty, a replacement will be made without interfering with the operation of the loom. When a replacement is eiected, a filled bobbin of yarn is transferred from the battery into the shuttle against the empty bobbin and thus the empty bobbin is expelled by the incoming iilled bobbin. In order to collect the empty bobbins as they are expelled from the shuttle, a suitable can or receptacle is disposed below the loom shuttle box, preferably in an unobstructing position relative to the aisles between the rows of looms. At regular intervals a bobbin truck is passed down these aisles to take up the empty bobbins collected in each can or receptacle.

It is an object of this invention to provide an improved bobbin receptacle detachably mounted on a loom and normally positioned out of the loom aisles while in receiving position, but which is capable of being swung or rotated into the loom aisle when the collected bobbins are being removed therefrom.

It is another object of this invention to provide a bobbin receptacle of the class described in combination with an adjustable bracket structure whereby the receiving position of the receptacle may be varied relative to the loom shuttle box.

It is another object of the invention to provide a bobbin box made of fabric and having a ring adapted to be inserted around the rim for supporting the same, in a swinging position.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in which- Figure 1 is a schematic plan View illustrating the arrangement of a plurality of looms in a mill so as to provide an aisle space therebetween;

Figurel 2 is an elevation, showing certain portions thereof in section, of a loom structure illustrating thev improved bobbin receptacle;

Figure 3 is a sectional plan view taken along the line 3 3 in Figure 2, showing in dotted lines the position of the bobbin receptacle when in an inoperative position;

Figure 4 is a vertical sectional view taken along the line 4-4 in Figure 3;

Figure 5 is an isometric view of the bottom structure employed in the bobbin receptacle;

Figure 6 is an exploded isometric view showing the means for supporting the bobbin receptacle;

Figure 7 is an isometric view showing a slightly modified form of a bobbin receptacle supporting means in association with a loom frame.

Referring more particularly to the drawings, the numeral I0 denotes a portion of a loom frame upon which is mounted a conventional battery bracket II in which is rotatably mounted a disk I2 as at I4. The periphery of the disk I2 is adapted to receive a plurality of lled bobbins of yarn I5 and during the operation of the loom the disk I2 and these bobbins I5 are advanced step by step to a lowermost transfer position.

The transfer of the lowermost bobbin I5 is effected by a conventional L-shaped transfer arm I1 pivoted as at I8 to the battery bracket. One leg of the L-shaped transfer arm Il has a dog I9 pivotally secured to the lower end thereof, which dog is engaged during transfer by a suitable bunter 20 carried by oscillating loom lay 2l. This loom lay has a shuttle box 22 on the upper end thereof for receiving a shuttle 23. It will be noted that the lay ZI and the shuttle box 22 are disposed immediately below the lowermost bobbin I5 during a transfer. The parts in Figure 2 are shown while a transfer is being effected, and at this time the lay 2| and bunter 20 are being moved to the left to thereby cause members I'I and I9 to rotate in a clockwise manner about the shaft I8. The rotation of member I1 serves to transfer the lowermost bobbin from the disk I2 into the shuttle 23. As the lowermost bobbin I5 enters the shuttle 23, the empty bobbin I5a is simultaneously removed therefrom, after which it falls downwardly against guide plate 25 and into a suitable receptacle therebelow. The parts, thus far described are conventional in automatic replenishing looms but it is thought necessary to describe this much of conventional structure, to more thoroughly understand the purpose of the present invention.

It is very desirable that the receptacle which collects these expelled bobbins be supported by the loom frame, in a manner whereby the contents may be easily removed therefrom. It is equally desirable that the receptacle be normally placed in a non-obstructing position -relative to the aisles or passageways between the rows of looms, so that trucks or other conveyances which are rolled down the aisle will not engage these receptacles. With these objects in View, the present receptacle has been swingably mounted about a vertical axis so that the receptacle may be swung laterally into the loom aisle when the contents are being removed therefrom and may be rotated out of the loom aisle and beneath the shuttle box when in a bobbin receiving position.

Figure 1 illustrates a typical floor plan arrangement of looms in a mill. It is here seen that the loorn frames I9 are arranged in rows, substantially alining their respective lays 2|,

thereby providing an aisle space between the rows. This aisle space is substantially parallel to the lays of the loom, and is used for accommodating trucks and the like.

In order to provide a bobbin receptacle Vwhich will not obstruct this aisle while'in a bobbin receiving position, a novel type of bracket 32 has been secured to the side of loom frame Ill adjacent aisle 35 by any suitable meansv such as ybolts 33. Bolts 33 are adapted to penetrate holesv34 in the bracket 32 and have the ends thereof threadably secured in the Yloom frame. The bracket .32 is U-shaped and whenA positioned on the loom frame the outstanding -1egs.32a and A321) are superposed in a horizontal position. These outstanding legs have vertically alined holes 35 therein for receiving a vertical leg 36 of a bag holding frame, broadly designated by the reference character 31. A horizontal portion 38 extends from the upper end of the vertical leg 3B and to this horizontal portion a downwardly inclined portion 39 is secured, which in turn has a horizontal portion Il@ extending from its end. An upwardly inclined portion M extends from the end of portion 4|, all of said portions 38, 39, 40 and .4| being bent so as to form a substantially rectangular frame. It will be noted that the end of portion 4| overlaps and rests kupon the portion 38. Therefore, when it is desired to insert a bag upon the frame 31, it is only necessary to pull upwardly on the end of member 4| `and insert the hem of the bag over the frame.

from the receptacle or if desired he may detach the entire assembly from the bracket 32 and pour the empty bobbins into another receptacle.

Figure 7 shows a slightly modified form of bracket structure for supporting the bag. In this form, a U-shaped bracket 5D is adjustably secured to the side of end frame I0, by any suitable means such as stud bolts 5|. These bolts penetrate the slot 52 in the bracket structure. Bracket has horizontal legs 53 and 54, said leg having vertically alined holes and 56 respectively therein for receiving leg 3B of the bag holder 31 previously described. The leg 53 has adjustably `secured thereto a plate 51 which in turn has a pair-of slots 58, each of which is penetrated by a screw 59, and these screws have their ends threadably secured in said leg 53 of the bracket.

'The upper edge of the plate 51 has a notch 60 therein into which the leg portion 38 of the bag holder or frame 31 is adapted to releasably nt when the vbag is in a position for receiving bob- In .thepresent disclosure, a bag 43 is provided,

which is preferably made of some flexible material such as canvas, rubber or the like. The upper open end of the bag structure 43, has a hem 44 formed thereon for receiving the portions 38, 39, 4|) and4l.

In order to make the. bottom of the bag structure 43 wear-resistant, so that the falling of the empty bobbins lea will not injure the same, a suitable rectangular bottom structure 45 is provided. This bottom structure may be made of any suitable material such as rubber, leather, wood, stiff fabric, metal or the like, and has secured thereto a U-shaped plate member 46 by any suitable means such as rivets or bolts 41. The legs of the U-shaped member 45 are secured to the vertical side-walls of the bag 43 by any suit- Vable means suchas bolts or rivets 48.

The bag holder together with Vits associated bag 43 is held in bobbin receiving position, that is bold line position, as shown in Figures 2 and 3 by means of a suitable notch 43 cut in the upper portion of bracket 32. This notch receives the horizontal portion 38 of the bag holding structure 31, and thereby releasably holds the bag and holder in positionbeneath-the shuttle box.` in a bobbin receiving position. When it -is desired to remove the contents from the bag structure, it is only necessary to lift the holder- 31 and bag-43 a slight amount vertically, and then rotate the same about vertically alined holes 35 as an axis until the bag and. frame are .disposed Within the aisle 30 between the looms. 'When in this position, an operator may removetheemptybobbins bins from the shuttle box. :The dotted line position of the leg member 38 shows the position of the frame when the parts are in this operative position, whereas the bold line position of parts 35 vand 38 show theposition of the bag when the same'is rotated into the aisle and out from beneath the shuttle box.

When it is desired to vary the locked position that the bag or receptacle will occupy while beneath the shuttle box, it is only necessary to loosen the screws 59 and then reposition plate 51 and its associated notch 60. After this is done,

.the screws 59, of course, are again tightened.

The Vertical position of the bag structure and frame may be varied in a similar manner, that is, by loosening the stud bolts 5| and then bodily moving the bracket 5|! vertically to the desired y position.
